How do I create a class or group?

1) Go to  Teams screen in People tab; tap Edit, New Team, and Done. Tap on new group name to see list. 

2) Tap on title at the top of the page (e.g. Group1) to edit the name (e.g.  First Period)

3a) For people that are already in Watches, just tap on them to include them and hit Done.  

3b) For people that are not, tap on Add New People at the bottom of the list. 

4a) You then have a choice: 

4a) EITHER tap Select From Contacts to choose from your device's contact list, 

4b) OR type the names into the big field, 

4c) OR copy and paste from another source. As it says, separate names with commas or returns (use quotes to include a comma within a name). So: John Doe, "John Dozer, MD", Michael Smith

5) hit Save to load those names into Watches.

After any name, you can add an email address in angle brackets. For example, John Smith<jsmith@company.com>. Conveniently, this is the format that email apps use, so you should be able to cut/paste directly from a To: or cc: line. 

Tip: If you have a master list of all people available, not grouped by teams, tap on All People in  Teams screen to copy and paste it into the import field to avoid adding everyone to a particular group. Then you can create each group and assign each person to the appropriate group(s).
